VEHICLE-CURTAINWINDOW STRUCTURE.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed March 31, 1915. Serial 1510. 18,369.

T 0 all whom 1' I? may concern Be it known that I. Burner: L. Kxr'nssx.

a citizen of the United States, residing at ings of vehicle curtains.

In automobiles hav ng tops, there is usually a sight-opening in the curtain at the rear. From one cause or another, this frequently becomes broken and is generally not replaceable except by removing the en tire curtain, etc.. because it is permanently fitted there-in. lVhen broken or damaged, the curtain presents an unsightly appearance; but the owner of the car cannot usually remedy the defect except at consid erable expense.

It is the obj'ect of my invention to provide an attachable and detachable windowstructureof simple and inexpensive construction and of such character that it may be easily mounted in place without the use of special tools and with great facility.

To this end, the invention resides in a curtain window-structure that may be. manually secured in place and which includes a transparent element (preferably of flexible material) to which is secured a. border or edging-element provided with or carrying means adapted to secure the structure to the edges or margins of the sight-opening in the curtain. The structure may also include a flap-element secured on one side of the transparent element along a line somewhat removed from the edge thereof whereby a sort of skirt or flap is presented and between which and the sheet the said curtain-margins are attachably secured. The fastening means may be of any appropriate form.

This invention in general seeks to provide a. structure of the kind described which .is particularly adapted for application to existing curtains wherein the window is damaged, or where it may be desired to sight-opening. From a strucit is of great simplicity it possesses the charactereilicient.

tural standpoint, and, operatively,

iitilized-surrounded by means for The invention has other objects in view and is characterized by other advanta es. as will be more apparent from the annexed drawings and the following: description.

It resides broadly; in the features of construction and in the related aggroupment of the different elements thereof. all as will be exemplified in the construction hereinafter set forth. and the scope of application of which will be indicated in the appended claims.

That the invention may be readily com-- prehended, drawings illustrating a possible embodiment and utilization of the same are hereto appended as a part of this disclosure, it being manifest that other possible embodiments and utilizations (employing the underlying principles of the ,invention) fall within the spirit thereof and within the ob jects contemplated thereby.

In the accon'ipanying drawings: Figure l is a View of a vehicle top with a curtain provided with my window-structure; Fig. 2 is a detached view of the structure, by itself; and Figs. 3 and 4 are fragmentary views, in section, sli'owing the details of the structure on a somewhat larger scale.

Referring to these drawings, the reference-clr acter 1 designates, generally, a vehicle top. This is provided with rear curtain 2 of any appro u'iate material and so ie. The curtain has a sightopen1ng 3. Ordr narily, this sight-opening contains a window more or less permanently secured therein. Hence, should it become damaged, it is practically impossible for an unskilled version to replace the broken window by a new one. It the aim of my invention to provide the curtain with a new window and one which can readily 'be applied by almost anyone. This consists, preferably and as shown, of a sheet of transparent material 4rpreferably celluloid, mica, or similar material, though glass may, if desired, be

attachmargins of the sight-openings. These means, preferably and as shown, include the following instrtunentalities: sewed or otherwise secured along the edges of the transparent sheet or window 4 is a border or edging element 5. In this in stance, it revealed a flexible strip having a portion 6 turned over the edge of the sheet and stitched thereto, as shown. The opposite edge -portion 7 is preferablv olded ing it to the 1111*! a ai st itself and is also Stitched as at s, to the sheet. There are, therefore, two lines of stitching.

()n the opposit side of the sheet is se-. ured 1111111 1 111 h rei ig te a flan element H. This is. preferably and as shown. a liefihle strip or hand which is stitched to the sheet at 1 that is, along a line sonu-what removed from the edge of the sheet. This: provides a five or flap-poi.- tion: and. between it and the surface of the sheet 1 there is presented a curtaiii-receiving space 11. Into this space. the edges and margins 1'.{ of the sight-opening in the 'curtain J are inserted. The curtain. sheet. edging and flap are then fastened together by appropriate means. In practice, I have foun d thgit the means herein illustrated are well adapted for this purpose and such means contemplate the f11ll0\\'il1f The edging, flap, etc, ha ing been perforated (in any suitable 111111111121") tastemug-elements are inserted into the perforations and their endsll clenched against an interposed washer 15. In this way. the curtain is clamped (so to speak) between the flap and windowssheet 4, while the edging protects the edge of the sheet.

To atford rigidity to the structure, I may, if desired, 'dis1msc a stitfening element 16, in the form of a wire (for example) in the edging: but this would ordinarily not be used where the curtain has to be folded or rolled though. even in this instance, it might be made in sections. and. thus. permit any desired or necessary rolling. etc.

lYhen it desired to apply my structure, a person may proceed asfollows: In the first place, the fragments and pieces of the broken window should beremoved. Then. if the sight-opening is of proper dimension to receive my structurcor, if not. it is quickly made so-said structure is placed in position: To this end, the fastening elements having first been removed from the structure, the edges and margins are carefully inserted into the space 11. Then, the flap is pressed against it and the fastening elements reinserted and made to extend through the curtain margins and clenched.

The edging, which forms a frame, may if desired, be of stiff material and, in fact, may be of metal. in which instance, I could place two of the frames at opposite sides of the transparent sheet and secured thereto and to each other in clamped relation, ho\ 'eve1 the edging would he leather, oilscloth. or other fabric.

From the foregoing. it will be perceived that I have devised. as an article of manut'acture. a manual1y-inscrtible curtainindow structure. preferably flexible in character. and including means for securing it in the sight-opening of a vehicle or other form of Curtain. It is exceedingly simple and compact in form, it is conveniently applied without the use of tools. and it is of attractive appearance.

It to be understood that all matter contained in the foregoing description and shown in the accompanying drawings intended to be illustrative merely and that the invention susceptible of a wide range of modification without a departure from its spirit.

What I claim is:

1, An attachable curtain window comprising a sheet of flexible and transparent material; a flexible i )1'11'(lQF-Oltllitlit secured around the edges of the sheet on one side thereof: and -a flap. composed of, flexi le material. secured in proximity to the edges of the.sheet on the opposite side thereof. to constitute with said sheet and border-element. a pocket for the reception of the edges of a sight-opening in a curtain.

:2. I11 combination with a curtain ha ing a sight opening provided with perforate edges; a window structure therefor comprising a flexible transparent member; a border secured around the edges of one side thereof; a flap secured around the edgeson the side opposite said border. to constitute with said border and window. :1 pocket for the reception of the edges of the sight opening in the curtain: said curtain. border, window and flap being provided with perforations adapted to register with the perforations in the curtain when the edges of the curtain aroundthe sight opening are disposed in the pocket; and a plurality of fastening elements adapted to be disposed in said PELfOLlItiODS to "secure the parts together.

In testimony whereof I atiix my signature in presence of two witnesses.
